Consumer Redressal

My father went to GOPAL RADIO CLINIC located in serampore, wishing to buy a refrigarator in exchange with our old one. We wished to buy a samsung 275 ltr fridge which we got with a price tag of around 24600/- and rs 1300 less on Rs 24600 in exchange with our old fridge from another shop(E-Zone). Now Gopal Radio CLINIC with a little bargain agreed to provide us the same with the same price tag of rs 24600 and rs 1500/- on rs 24600 on exchange with our old fridge. We din\'t knew the exact model no. throughout .Now when my father signed on the cash memo unaware of the exact model no. for 275ltrs. The shop wrote the model no. a size below than what we wished for . Now after delivery we noticed this fact and now they are denying on the fact that they have said to provide us 275 ltr fridge. We are helpless. Model No provided :SAMSUNG RT26FAJFAPX(253 ltrs) MODEL NO WE WISHED : SAMSUNG RT28FAJFAPX (275 ltrs)
